To graph: the given inequality.

Answer to Problem 8E
Explanation of Solution
Given:
Calculation:
Consider the inequality
Graph the inequality
To graph the inequality
Clearly, the points on the line itself do not satisfy the inequality because, the inequality contains
To determine whether the above or below region of the line satisfies the inequality, use the test points
Substitute the coordinates of each point in the inequality and check whether the result satisfies the inequality.
The computations are tabulated as shown below:
Test point | Conclusion | |
Not a part of the graph | ||
Part of the graph |
From the above table, observe that the points below the line are satisfies the inequality.
So, shade the region below the dashed line on the graph.
The graph of the inequality
Conclusion:
Therefore, the graph of inequality is drawn.

- The spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
